Remove unnecessary with_temporary_connection_pool calls
Remove unnecessary with_temporary_connection_pool calls

While debugging a different problem I'm working on I realized that this
method `with_temporary_connection_pool` isn't necessary in most of the
cases we're using it for.

Anywhere we establish new connections inside the block won't throw away
those new connections. I also removed this from places that can use the
existing connection and don't need a new temporary pool. I'm not sure if
this file was using it in many places because of copy / paste or real
issues that are no longer present.
